If your heart beats too slowly or gets out of rhythm, a pacemaker can send an electrical pulse to that muscle and get it back on track. To do that, pacemakers need generators with batteries, and ...

"Mechanical and electrical energy are linked and can be exchanged back and forth," said lead study author Babak Nazer, M.D., an associate professor of medicine at the University of Washington in ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

Researchers have developed and tested for the first time in vivo a miniaturized, battery-free pacemaker that supports optical and electrical multisite stimulation. The new device is powered wirelessly ...

The Association for the Advancement of Medical Instrumentation (AAMI) officially announces the publication of a new guidance document on battery longevity management for implantable cardiac pacemakers ...

Scientists have designed a temporary, battery-free pacemaker that can be broken down by the patient’s body when its work is done, the latest advance in the emerging field of bioelectronics. In a paper ...

Pacemakers have a problem — and that’s not something you want to hear about a medical device which literally helps a person’s heart to continue to beat normally. The problem, simply, is that they rely ...

Clinical pacemakers save lives. Implanted in patients’ hearts to keep them beating regularly, the devices are an important part of modern healthcare in the fight against potentially fatal arrhythmias.

Millions of people have benefited from pacemakers since the first one was implanted in 1958, but the basics facets of the design have remained unchanged. These devices are still battery-operated, with ...

Atrial fibrillation – a form of irregular heartbeat, or arrhythmia – leads to more than 454,000 hospitalizations and nearly 160,000 deaths in the United States each year. Globally, it is estimated ...

An experimental, leadless pacemaker housing is able to partially recharge the device’s battery by generating electrical energy from heartbeats. The device generated about 10% of the energy needed to ...
